Deformation twinning is an important plastic carrier competing with the ordinary dislocation
slip in a broad class of crystalline solids, which critically controls the mechanical properties …

In the past decade, mechanical metamaterials have garnered increasing attention owing to
its novel design principles which combine the concept of hierarchical architecture with …

Abstract In 1903, Alexander Graham Bell developed a design principle to generate
lightweight, mechanically robust lattice structures based on triangular cells; this has since …

The strength of lightweight mechanical metamaterials, which aim to exploit material-
strengthening size effects by their microscale lattice structure, has been limited by the …

Diamonds have substantial hardness and durability, but attempting to deform diamonds
usually results in brittle fracture. We demonstrate ultralarge, fully reversible elastic …

An optoelectronic material with a spatially varying bandgap that is tunable is highly
desirable for use in photovoltaics, photocatalysis and photodetection. Elastic strain has the …

Recent experiments on nanostructured materials, such as nanoparticles, nanowires,
nanotubes, nanopillars, thin films, and nanocrystals have revealed a host of “ultra-strength” …

Despite decades of studies of calcium-silicate-hydrate (CSH), the structurally complex
binder phase of concrete, the interplay between chemical composition and density remains …

Abstract Deformation twinning,,,,, in crystals is a highly coherent inelastic shearing process
that controls the mechanical behaviour of many materials, but its origin and spatio-temporal …

Achieving high elasticity for silicon (Si) nanowires, one of the most important and versatile
building blocks in nanoelectronics, would enable their application in flexible electronics and …
